The history of Yangqiao River can be traced back to the Tang Dynasty, when Changde City was low-lying and vulnerable to floods. In order to prevent disasters, local residents began to build dams and drainage channels, and later people called this river Yangqiao River. According to the History of Tongjian, there was a big flood in Changde during the Tang Gaozong period, and Yangqiaohe played a very important role at that time. Later, Yangqiao River became a trade channel to the outside world and provided a safe drinking water source for urban residents. Yangqiao River is an important part of Changde's history and culture and one of the lifelines of the city.
